We argue that nonfamily managers exhibit lower entrepreneurial behavior than family managers, particularly after the founder¡¯s departure from the business. Moreover, we identify an expanded set of factors through which family firms can facilitate nonfamily managers¡¯ entrepreneurial behavior, including monitoring, incentives, distributive justice, access to the top management, and job control perceptions. We test these hypotheses in a sample of 296 family firm managers, contributing new insights on nonfamily managers and corporate entrepreneurship in family firms %K bounded rationality %K bounded reliability %K transaction cost economics %K (non)family managers %K entrepreneurial behavior %U https://journals.sagepub.com/doi/full/10.1177/1042258718796085
